It seems that many people who would have written an article on their own blog are writing for medium instead. It seems like the HN community will become more discriminate in only upvoting the good articles from medium.
I mostly posted this there to try it out but if there is something wrong with doing so (other than seeing a tld of medium.com), I'd really appreciate hearing about it.
Comparable content from other sources would normally not gain nearly as many upvotes in as short a time as the medium.com stuff does.
You know there is something afoot when a medium.com story gets more upvotes and appears on the homepage seconds after being posted contrasted with for instance an article written by Joe Armstrong or phys.org article about the visualization of chemical bonds being formed and broken.
That's not proof by a long shot but there is definitely something going on there.
